We had a bug where, if you were riding a motorcycle then accidentally unmounted a motorcycle in the same room that you were not riding, it would let you walk off and a ghost rider would remain making the motorcycle unusable. This is now fixed and you will be told that you can't dismount a motorcycle you are not on.

I want to point out that, while it might seem a funny joke, you are not really caged and unable to do anything while waiting for your history to be approved. Only auto-payment jobs are blocked while waiting. That's like less than 10% of the game.
